SPECIFICATION forming part of Letters Patent No. 361,182, dated Aprill2, 188'7. Y

Application filed July 13, 1886.

To all whom it may concern..-

Be it known that I, GEORGE T. PrLLINGs, a citizen of theUnited States,residing at. Baltimore, in the State of Maryland, have invented certainnew and useful ImprovementsinWatertltngines, of which the following isa'specificaion. My invention relates to an oscillatingcylinderwater-engine; and it consists in cert-ain novel parts and combinations,which are illustrated in the accompanyingV drawings, and hereinafterdescribed and claimed.

In the drawings, Figure l is an elevation in which the greater part ofthe engine is shown in section. Figs. 2 and 3 are verticalcross-sections, showing one cylinder in two positions and exhibit-ingthe effect of the cylinders os cillation on the port-s.

The letter Al designates a water-box provided with a waste-water outlet,b. |lwo stationary blocks or supports, C, are fixed in the water-box,and a horizontal cylinder, D, is fixed to said blocks or supports. Thehorizontal cylinder D is stationary, and is open at one or both ends, e,the said opening having a capacity equal to the cross-area of thestationary cylinder. The cylinder conta-ins a separate internalwater-supply passage, F, formed integral with the cylinder D by castingthe cylinder and passage in one piece; or said passage may be securedwithin the cylinder at one side. The cross-dimension of the watersnpplypassage F is very much less than that of .the stationary cylinder D. Theends g of the fluid or water supply passage are closed,

`and a supply tube or pipe, F', enters through the cylinder D andconnects with the watersupply passage F.

The oscillating cylinders H have pistons, and are mounted verticallyupon the stationary cylinder D, and each one is secured thereto by acollar, I, which is fitted around the cylinder D so as to rock or turnthereon, whereby the piston-cylinders H, supported, as they are, uponthe stationary cylinder, may oscillate.

A crank-shaft, K, is supported on suitable standards, L, and piston-rodsm connect the pistons n directly with the cranks o. The shaft K carriesa'balance-wheel, p, and a drivepulley. Q-

lhe exhaust or waste water is discharged from the piston-cylinders Hinto the stationary Serial No. 207,858. (No model.)

| cylinder D, from whence it flows out at the open end cinto the boX A.It is obvious, however, that instead of having an open end e, from whichthe water may iiow, the stationary purpose.

The internal dimension of the cylinder D, which serves as anexhaust-receptacle for the waste water which comes from the cylinders H,is equal to or exceeds the capacity of the said cylinders This is ofgreat importance, as thereby, when the water in any one cylinder hasforced the piston up, and when the cylinder has oscillated, all thewater in said cylinder may be promptly discharged,and thus avoid thedetrimental backlash or reflex action. the boX A for holding water isgreater than exhaust-water in the cylinder D may iow or dischargepromptly and without retardation into the said water-box.

A portion, I', of the collar I constitutes the head of the oscillatingcylinder, and this portion is provided with an inletport, r, and twooutlet-ports, s. The stationary cylinder D has a supply-port, r', whichcommunicates from the water-supply passage F, and on the upincident withthis supply-port r', as shown in Fig. 3. Water under pressure therebyenters the oscillating cylinder H. The stationary cylinder has twodischargeports, s', which communicate directly with the interiorthereof, and on the downstroke of the piston n the outlet-ports s willbe coincident with the discharge-ports s', as lwill be readilyunderstood. Thereby the water in the oscillating cylinder is exhaustedand finds an immediate outlet into the stationary cylinder, from whenceit iows off, as before stated.' No valves are ernployed.

In the present instance two oscillating cylinders are shown; but threeor four may be employed in like manner. My invention,

therefore, is not limited to any particular number of such cylinders.

I am aware that itis not new to employ in this class of engines a fixedcylinder with an internal water-passage; neither is it new to secure theoscillating piston thereon by means of a collar having portscommunicating with Another feature is, that the capacity of stroke ofthe piston n the inlet-port o* is cocylinder may have a side opening forthis that of the exhaust-cylinder D, whereby the ICO the water-passageand iixed cylinder, and such I do not claiin, broadly; but I am notaware t-hat it is old to construct an engine of this character with aninlet-pipe leading directly into the water-passage of the fixed cylinderand permitting the exhaust-water to escape from the water-box, as hereindescribed and shown, the benet resulting from this construct-ion beingthat the head of water fed to the water-passage F is directly exerted onthe piston to compel the upstroke thereof. The facility of keeping aconstant and uniform supply of water is readily apparent.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- In a double-cylinder oscillatingwater-engine, the water-boxes A, having outlets, in colnbination withthe stationary cylinders D in said boxes, each of said cylinders beingprovided with the supply-passage F, closed at its ends, the inlet-pipeF, leading into said passage F from above and outside of thepiston-cylinder H, the said cylinder H having collar surrounding thestationary cylinder D, the piston n, and connections, the shaft K, thecollar I, attached to said cylinder H and having the upper portion, I',the latter having ports 1*,8, and s, the said cylinder D having ports ss', adapted to register with the ports s s on the downstroke of thepiston, whereby the exhaust-water from the cylinder H ilows into thecylinder D, and the supply-passage F, having port i", adapted toregister with the port r, whereby the water flows from the passage Finto the cylinder H, so as to make the upstroke of the piston n, thesaid pistons being connected to the said crank-shaft K, so as to haverising and falling motion alternately, all substantially as shown anddescribed.

In testimony whereof I aiX my signature in the presence of twowitnesses.
